Definitions
- the invention relates to a safety device according to the preamble of patent claim 1.
- the blocking device in a first embodiment consists of a locking lug which positively connects the coupling device with the actuator and the adjusting lever to a stationary housing as soon as it has been moved into the locked engagement position by the operator by means of the locking handle .
- the blocking device in a second embodiment, consists of a Hirth toothing, a part of which is firmly connected to the coupling device and the other part is fixedly connected to the housing, these parts being displaced by the locking handle when the coupling device is displaced the operator in contact in the locked engagement position.
- the operator When using the first-mentioned, structurally particularly simple embodiment, the operator must pay close attention that, on the one hand, the normal engagement position of the Clutch, on the other hand, but not its disengaged position is set if he wants to make a change to the drive.
- the above-mentioned blocking device with the Hirth toothing avoids this difficulty, because the operator can move the actuating lever in the coupled state of the coupling with a somewhat increased effort when he exerts the force with which he lock lever 4 in the release position holds up, wears off a little.
- the second embodiment is disadvantageous in that it requires an increased construction effort and only allows a gradual change in the drive.
- the object of the invention is to provide a safety device according to the preamble of claim 1, which is characterized both by a simple construction and by the possibility of a continuously variable changeability of the travel drive.
- the operator just as in the known safety device with a Hirth toothing as a blocking device, the operator only has to release a little the force with which he holds up the locking handle in the release position when he actuates the adjusting lever in the coupled state of the clutch ⁇ want to move to change the drive, and he can then, unlike the known safety device, continuously adjust. A small release movement of the locking handle is enough to move the control lever with a moderate amount of force.
- the blocking device in the safety device according to the invention is structurally much simpler than in the known safety device with the Hirth serration
- Fig.l seen the safety device in longitudinal section from the side
- FIG. 2 shows the top view of the safety device according to FIG. 1,
- FIG. 4 shows the top view of FIG. 3.
- FIG. 1 to 4 has a housing 1, which is rigidly attached to a vibrating roller in the area of a guide bracket 2, of which only the end of a guide drawbar 3 attached to it for manual guidance is shown in FIG. 1, apart from the guide bracket 2 is to which the guide bracket 2 is attached.
- a locking handle 4 is also pivotally mounted on the drawbar 3 so that, when no force is exerted on it, it assumes an angular position with respect to the guide bracket 2, in which its end 4a facing away from the drawbar 3 assumes a lower altitude than the handle part 2a of the bracket 2.
- the outer contour of the locking handle 4 is located within the inner contour of the guide bracket 2, both in a switch-off position shown in FIGS. 1 and 3 and in all other positions up to one.
- the locking handle 4 is pivotable about an axis of rotation. The switch-off position and the further positions of the locking handle 4 are discussed in more detail below.
- the housing 1 has a transverse bore 6 and is attached to the vibrating roller so that the transverse bore 6 is above a part attached to the locking handle 4
- a Bowden cable 8 leading to the drive (not shown), for example a hydraulic pump, of the vibrating roller extends into the housing 1.
- the Bowden cable 8 is firmly attached to a rack, which is only shown schematically and is longitudinally displaceable in the housing 1 9 connected, which is loaded by a spring 10 supported between it and a housing surface 13 into the housing into an end position, which is fixed by a stop 11 fixed to the housing.
- the toothed rack 9 meshes with a spur gearwheel 14, which is seated at the inside of the housing of an axis 15, which is rotatably mounted in the lower part of the transverse bore 6 with respect to FIG. 1 and protrudes downward from the housing 1.
- a first disc 25 with teeth 25a arranged coaxially around the axis 15 on the free end face is fastened at the end face, the teeth of which face a second disc 26, which is connected to the locking handle 4 in a form-fitting but height-adjustable manner.
- the second disk 26 is provided on its side facing the teeth 25a with a gi-mni elastic coating 26a firmly connected to it.
- the gear 14 is together with the axis 15 by means of the locking lever 4 in the limits can be moved back and forth from its range of motion in the housing 1, and it has such a height that it remains in engagement with the rack 9 at all times.
- the gear 14 is opposite a rotary head 16, which is fixedly attached to the lower end of a shaft 17 aligned with the axis 15, which is rotatably mounted in the upper part of the transverse bore 6 with respect to FIG. 1 and protrudes upwards from the housing 1.
- a rotary head 16 which is fixedly attached to the lower end of a shaft 17 aligned with the axis 15, which is rotatably mounted in the upper part of the transverse bore 6 with respect to FIG. 1 and protrudes upwards from the housing 1.
- an adjusting lever 18 extending perpendicular to it is attached outside the housing.
- a compression spring 19 is arranged between the rotary head 16 and the gearwheel 14, which presses these parts apart in the axial direction of the axis 15 and the shaft 17 and tries to keep them in abutment on stop faces 20 fixed to the housing.
- Parallel to the axial direction of the shaft 17 extend from the free end face of the rotary head 16 from two coupling pins 21 to the gear 14, which is provided with two matching blind holes 22, into which the pins 21 in a predetermined relative angular position between the gear 14 and the turret 16 can intervene when the gear 14 by means of the locking lever
- the arrangement is such that the pins 21 are located just outside the blind holes 22 when the locking handle 4 assumes its lowest position, the switch-off position, shown in FIG. 1.
- the gearwheel 14 with the blind holes 22 and the rotary head 16 with the pins 21 together form a switchable coupling which can be actuated by means of the locking handle 4 and via which the actuating lever 18 can be positively connected to the rack 9 forming the actuator of the device.
- Such a connection is made by lifting the blocking Handle 4 accomplished from the position shown in Fig. 1 ' and Fig. 3, wherein initially a normal engagement position for the subsequent movement between the actuating lever 18 and the rack 9 comes about.
- the safety device according to FIGS. 1 to 4 works as follows:
- the operator For the travel-effective operation of the actuating lever 8, the operator must first set the normal engagement position of the clutch 24 with the locking handle 4, but make sure that the pressure between the teeth 25a and the lining 26a does not become too great, that is to say not erroneously that Lock position is reached. This practically takes away the possibility of simply tying the locking handle 4 to the guide bracket 2.
- the disc 25 is adjusted with respect to the locking handle 4 so that the teeth 25a and the rubber-elastic covering 26a have a clear mutual distance in the switched-off position of the locking handle 4.
